我正在对文本体运行文本字符串,以确定该文本字符串是否存在于特定上下文中(在本例中,在h2标题标记中)。我可以举一个例子,它可以完美地在本地主机安装我的应用程序,在win7上运行PHP 5.3与XAMPP
然而,当我在一个实时http站点上测试相同的内容时,在HostGator上运行PHP 5.3.8,我在相同的测试中得到假阴性。
任何想法?代码如下…
Keyword: Flirttipps für Männer
Content: <h2>Flirttipps für Männer</h2>
function doTheParse($heading='h2', $post) {
//$content = $post->post_content;
$content = '<h2>Flirttipps für Männer</h2>';
$keyword = sanitize_string( trim(strtolower(getKeyword($post))) );
$keyword = sanitize2($keyword);
@$dom = new DOMDocument;
@$dom->loadHTML(sanitize_string( strtolower($content) ));
$xPath = new DOMXPath(@$dom);
switch ($heading) {
case "img-alt":
return $xPath->evaluate('boolean(//img[contains(@alt, "'.$keyword.'")])');
default:
return $xPath->evaluate('boolean(/html/body//'.$heading.'[contains(.,"'.$keyword.'")])');
}
}
function getKeyword($post) {
global $spec;
$myKeyword = get_post_meta($post->ID, 'my_keyword', true);
if(isset($spec['keyword_default']) && $myKeyword == ""){$myKeyword = $post->post_title;}
$myKeyword = htmlspecialchars_decode($myKeyword);
return " ".$myKeyword;
}
function sanitize_string( $content ) {
$regex = '/( ['x00-'x7F] | ['xC0-'xDF]['x80-'xBF] | ['xE0-'xEF]['x80-'xBF]{2} | ['xF0-'xF7]['x80-'xBF]{3} ) | ./x';
return preg_replace($regex, '$1', $content);
}
function sanitize2($s) {
$result = preg_replace("/[^'p{Latin}0-9&'-]+/u", " ", html_entity_decode($s, ENT_QUOTES));
return $result;
}
检查区域设置,例如setLocale()。根据语言设置,许多函数的工作方式不同。
